An interposer holds spring probes in the proper position to establish an electrical connection between a printed circuit board (PCB) and a test head for a product handling shorts and opens test machine. As typically implemented, the spring probes are susceptible to damage and falling out of the interposer while being transported. The placing of the interposer into a carrier prevents these problems, as described below. As seen in Fig. 1, in the Section A-A view, the spring probes 1 are slip-fitted into the drilled holes 2 of a top frame 3 of the interposer 4. The probes 1 extend down to and through the drilled holes 5 of a bottom frame 6. The interposer 4 is an assembly and consists of a top frame 3 and a bottom frame 6 which are separated by a spacer 7.
